Abstract: Based on the study of technological parameters of coal fly ash in laboratories, the influencing regularity of different ingredients and forms of coal f ly ash on its resourceful property was disclosed. The optimum experiment for geti ng rid of carbon harmfulness to resourceful property of coal fly ash was initial ly finished. The cooperating rate of decarbonized coal fly ash concrete was researched and used to fulfil the pavement repair work. The result shows that decarbonized coal fly ash can o bviously improve the working property of the concrete. Both practical road convey ance and technological function can satisfy the demands of pavement engineering. Both the economic and environmental benefit is enormous.

Keywords: coal fly ash; resourceful property; decarbonisation; pavement engineering
